Methods and compositions for cDNA synthesis and single-cell transcriptome profiling using template switching reaction

ABSTRACT

This application discloses methods for cDN′A synthesis with improved reverse transcription, template switching and preamplification to increase both yield and average length of cDNA libraries generated from individual cells. The new methods include exchanging a single nucleoside residue for a locked nucleic acid (INA) at the TSO 3′ end, using a methyl group donor, and/or a MgCb concentration higher than conventionally used. Single-cell transcriptome analyses incorporating these differences have full-length coverage, improved sensitivity and accuracy, have less bias and are more amendable to cost-effective automation. The invention also provides cDNA molecules comprising a locked nucleic acid at the 3′-end, compositions and cDNA libraries comprising these cDNA molecules, and methods for single-cell transcriptome profiling.

The present application is a U.S. national phase application of International Application No. PCT/US2014/052233, filed Aug. 22, 2014, which in turn claims priority to U.S. Provisional Patent Application Ser. No. 61/869,220, filed Aug. 23, 2014, the contents of both of which are hereby incorporated by reference in their entireties.

FIELD OF THE INVENTION

The present invention relates to methods for synthesis of double stranded cDNA with improved yield and average length, and cDNA molecules synthesized and cDNA libraries generated from individual cells.

BACKGROUND OF THE INVENTION

Single-cell gene expression analyses hold promise to characterize cellular heterogeneity, but current methods sacrifice either the coverage, sensitivity or throughput. Several methods exist for full-length cDNA construction from large amounts of RNA, including cap enrichment procedures (Maruyama, K. & Sugano, S., Gene 138, 171-174 (1994); Carninci, P. & Hayashizaki, Y., Meth. Enzymol. 303, 19-44 (1999); Das, M., et al., Physiol. Genomics 6, 57-80 (2001)), but it is still challenging to obtain full-length coverage from single-cell amounts of RNA. Existing methods use either 3′ end polyA-tailing of cDNA (e.g., Tang, F. et al., Nat. Methods 6, 377-382 (2009); Sasagawa, Y. et al., Genome Biol. 14, R31 (2013)) or template switching (Zhu, Y. Y., et al., BioTechniques 30, 892-897 (2001); Ramsköld, D. et al., Nat. Biotechnol. 30, 777-782 (2012)), whereas other methods sacrifice full-length coverage altogether for early multiplexing (Islam, S. et al., Genome Res. (2011). doi:10.1101/gr.110882.110; Hashimshony, T., et al., Cell Rep. 2, 666-673 (2012)). It has recently been shown that Smart-Seq, which relies on template switching, has more even read coverage across transcripts than polyA-tailing methods (Ramsköld, D. et al., Nat Biotechnol. 30, 777-782 (2012)), consistent with the common use of template switching in applications designed to directly capture RNA 5′ ends, including nanoCAGE (Plessy, C. et al., Nat. Methods 7, 528-534 (2010)) and STRT (Islam, S. et al., Genome Res. (2011). doi:10.1101/gr.110882.110). Single-cell applications utilizing template switching are dependent upon the efficiency of the reverse transcription, the template switching reaction, and a uniform polymerase chain reaction (PCR) preamplification to obtain representative cDNA in sufficient amounts for sequencing. Despite the widespread use of these reactions, no systematic efforts to improve cDNA library yield and average length from single-cell amounts have been reported.

SUMMARY OF THE INVENTION

The present invention provides improved methods for synthesis of cDNA, in particular, in the reverse transcription, template switching and preamplification of single cell applications utilizing template switching reactions, to increase both yield and average length of cDNA libraries generated from individual cells.

In a particularly preferred embodiment, the method comprises use of methyl group donor betaine in combination with an increased concentration of MgCl₂, which has shown a significant positive effect on the yields of cDNA.

In another embodiment, the present invention provides a method of increasing the average length of a preamplified cDNA, comprising administering dNTPs prior to the RNA denaturation rather than in the reverse transcriptase (RT) master mix.

EXAMPLES Example 1

Methods

Experiments Using Total RNA

RNA experiments were performed using the Control Total RNA supplied with the SMARTer® Ultra Low RNA Kit for Illumina Sequencing (Clontech), extracted from mouse brain. One microliter of a 1 ng/μl solution was used in each experiment and mixed with 1 μl of anchored oligo-dT primer (10 mM, 5′-AAGCAGTGGTATCAACGCAGAGTACT₃₀VN-3′, where “N” is any base and “V” is either “A”, “C” or “G”) and 1 μl of dNTP mix (10 mM, Fermentas), denaturated at 72° C. for 3 min and immediately placed on ice afterwards. Seven μl of the first strand reaction mix containing 0.50 μl SuperScript II RT (200 U ml-1, Invitrogen), 0.25 μl RNAse inhibitor (20 U ml-1, Clontech), 2 μl Superscript II First-Strand Buffer (5×, Invitrogen), 0.25 μl DTT (100 mM, Invitrogen), 2 μl betaine (5 M, Sigma), 0.9 μl MgCl₂ (100 mM, Sigma), 1 μl TSO (10 μM, the complete list of the oligos can be found in Table S1) and 0.1 μl Nuclease-free water (Gibco) were added to each sample. Reverse transcription reaction was carried out by incubating at 42° C. for 90 min, followed by 10 cycles of (50° C. for 2 min, 42° C. for 2 min). Finally, the RT was inactivated by incubation at 70° C. for 15 min.

PCR Pre-Amplification

In the original Smart-Seq protocol purification with Ampure XP beads is performed after first strand cDNA synthesis. PCR is then carried out directly on the cDNA immobilized on the beads, after adding 2 μl Advantage 2 Polymerase Mix (50×, Clontech), 5 μl Advantage 2 PCR Buffer (10×, Clontech), 2 μl dNTP mix (10 mM, Clontech), 2 μl IS PCR primer (12 μM, Clontech) and 39 μl nuclease-free water to a final reaction volume of 50 μl. In the present examples the cDNA was not purified after RT but just added the same PCR master mix, taking into account that the volume after first strand cDNA synthesis is 10 μl and adjusting the amount of water accordingly. Reaction was incubated at 95° C. 1 min, then cycled 15 times between (95° C. 15 sec, 65° C. 30 sec, 68° C. 6 min), with a final extension at 72° C. for 10 min.

A second modification that significantly improved cDNA yield was the replacement of Advantage 2 Polymerase mix with KAPA HiFi HotStart ReadyMix (KAPA Biosystems). Purification after first strand cDNA synthesis was omitted also in this case. The PCR master mix had the following composition: 25 μl KAPA HiFi HotStart ReadyMix (2×, KAPA Biosystems), 1 μl IS PCR primers (10 mM, 5′-AAGCAGTGGTATCAACGCAGAGT-3′) and 14 μl nuclease-free water (Gibco). The program used was as follows: 98° C. 3 min, then 15 cycles of (98° C. 15 sec, 67° C. 20 sec, 72° C. 6 min), with a final extension at 72° C. for 5 min.

Regardless of the PCR protocol used, PCR was purified using a 1:1 ratio of AMPure XP beads (Beckman Coulter), performing the final elution in 15 μl of EB solution (Qiagen). Library size distribution was checked on a High-Sensitivity DNA chip (Agilent Bioanalyzer) after a 1:5 dilution. The expected average size should be around 1.5-2.0 kb and the fraction of fragments below 300 bp should be negligible. To evaluate the performance of the different modifications introduced in the protocol, the amount of cDNA comprised in the interval 300-9000 bp in the Agilent Bioanalyzer plot was assessed.

Tagmentation Reaction and Final PCR Amplification

Five nanograms of cDNA were then used for the tagmentation reaction carried out with Nextera® DNA Sample Preparation kit (Illumina), adding 25 μl of 2× Tagment DNA Buffer and 5 μl of Tagment DNA Enzyme, in a final volume of 50 μl. Tagmentation reaction was incubated at 55° C. for 5 min, followed by purification with DNA Clean & Concentrator™-5 kit (Zymo Research) with a final elution in 20 μl Resuspension Buffer (RSB) from the Nextera® kit. The whole volume was then used for limited-cycle enrichment PCR, along with 15 μl of Nextera® PCR Primer Mix (NPM), 5 μl of Index 1 primers (N7xx), 5 μl of Index 2 primers (N5xx) and 5 μl of PCR Primer Cocktail (PPC). A second amplification round was performed as follows: 72° C. 3 min, 98° C. 30 sec, then 5 cycles of (98° C. 10 sec, 63° C. 30 sec, 72° C. 3 min). Purification was done with a 1:1 ratio of AMPure XP beads and samples were loaded on a High-Sensitivity DNA chip to check the quality of the library, while quantification was done with Qubit High-Sensitivity DNA kit (Invitrogen). Libraries were diluted to a final concentration of 2 nM, pooled and sequenced on Illumina HiSeq 2000.

Single-Cell cDNA Isolation

Single HEK293T (human), DG-75 (human), C2C12 (mouse) and MEF (mouse) cells were manually picked under the microscope after resuspension in PBS. Volume of liquid was kept as low as possible, usually below 0.5 μl and preferably below 0.3 μl. Cells were then transferred to a 0.2 ml thin-wall PCR tube containing 2 μl of a mild hypotonic lysis buffer composed of 0.2% Triton X-100 (Sigma) and 2 U/μl of RNAse inhibitor (Clontech). Cells already picked were kept on ice throughout the process or stored at −80° C. if not used immediately. All the downstream steps were the same as when using total RNA (see above), with the only exception of the quality control with the High Sensitivity DNA chip, where samples were loaded pure (without dilution), due to the limited amount of cDNA obtained from RT in single cells.

When working with total RNA it was observed that cDNA yield could be increased using a double amount of TSO or different combinations of TSOs and PCR enzymes (data not shown). To validate this finding, some experiments on HEK293T cells were repeated using different amounts of TSO (1 or 2 μl of a 10 μM solution), TSO types (rGrGrG, rGrG+G or rGrG+N) or PCR enzymes (KAPA HiFi or Advantage 2). Sequencing results for the most significant comparisons are reported in Figures S2-S7. The final protocol (i.e. “optimized”) refers to the one using only 1 μl of the 10 μM rGrG+G TSO and KAPA HiFi HotStart ReadyMix as enzyme in the first PCR (without AMPure XP bead purification).

Smart-Seq Experiments

To evaluate and compare the performance of the present method, cDNA libraries were generated with the same total RNA and single cells using the Smart-Seq protocol, following manufacturer's instructions (see Clontech manual). After PCR pre-amplification, 5 ng of cDNA were used for the tagmentation reaction and processed exactly in the same way as described above.

Statistical Analyses of cDNA Yield and Length

Performances of the different protocols were evaluated with regard to cDNA yield and average cDNA length according to the Bioanalyzer in the range of 3009,000 bp. For mouse brain total RNA samples, each experimental variable was evaluated in a pairwise manner selecting a set of experiments where all other variables are identical. Within that set of experiments, the significance for a change in yield or length, between the two variables, was evaluated using Student's t-test and Wilcoxon rank sum test (Table 1, sheet B).

In the HEK293T cell experiments each optimized experimental setting was compared to each other, as well as to the SMARTer® protocol, using Student's t-test and Wilcoxon rank sum test (Table 3, sheet B). All analyses and figures were produced with using R.

Read Alignments and Gene Expression Estimation

Single-cell libraries were sequenced with Nextera dual indexes (i7+i5) on an Illumina HiSeq 2000, giving 43 bp insert reads after demultiplexing and removing cellular barcodes. The reads were aligned to human (hg19) or mouse (mm10) genomes using STAR v2.2.0 (Dobin et al. Bioinformatics 2013 29(1): 15-21) with default settings and filtered for uniquely mapping reads. Gene expression values were calculated as RPKM values for each transcript in Ensembl release 69 and RefSeq (February 2013) using rpkmforgenes (Ramsköld et al. PLoS Comp Biol., 5, e1000598, 2009).

Single-Cell RNA-Seq Sensitivity and Variability

Analyses of gene detection in single HEK293T cells (FIG. 2A, FIGS. 5A, and 7A) were calculated over all possible pairs of technical replicates from each experimental setting. Genes were binned by expression level in the two samples, and were considered detected if the RPKM was above 0.1 in both samples. The mean for all possible pairs of technical replicates within a group was used together with standard deviation using the adjusted Wald method. Analyses of variation (FIG. 2B and FIGS. 5B & 7B) were also calculated on pairs of samples, binning genes by the mean of log expression, excluding genes below 0.1 RPKM in either sample. As gene expression levels across single cells are often log normally distributed (Bengtsson Genome Res 2005 15(10): 1388-1392), absolute difference in log₁₀ expression values and s.d. were calculated by multiplying mean difference in a bin with 0.886.

Analyses of Read Coverage and GC Tolerance

Gene body coverage was calculated using the RSeQC-2.3.4 package (Wang, Wang and Li. Bioinformatics 2012; 28(16):2184-5) for the longest transcript of all protein coding genes (FIG. 2E and FIG. 8). Gene detection at different GC-content was calculated using longest transcript for all protein coding RefSeq genes that were binned by GC-content into 10 equal sized bins, and the numbers of genes with no detection, or detection at different RPKM cutoffs were calculated (FIG. 2D and FIG. 6).

Read Peak Analyses

Some genes displayed unexplained peaks with high density of reads within the gene body. To identify these regions, the gene bodies of each gene were divided into 101 equally sized bins and each gene with at least one bin with >5 standard deviation read density over the mean read distribution within that gene. In these analyses genes with low expressed genes (those with fewer reads than around 2,000-10,000 reads depending on the sequencing depth per cell) were discarded. The number of such genes in each cell is represented in FIG. 9A. And the genes with peaks in the highest number of HEK239T cells are displayed as heatmaps in FIG. 9B illustrating that the peaks are consistently found at the same position in all experiments.

Example 2

To improve full-length transcriptome profiling from single cells, a large number of variations to reverse transcription, template switching oligonucleotide (TSO) and PCR preamplification (in total 457 experiments) were evaluated, and the results were compared to commercial Smart-Seq (hereafter called SMARTer®) in terms of cDNA library yield and length (Table 1). Importantly, modifications were identified that significantly increased both cDNA yield and length obtained from 1 ng of starting total RNA (Table 1).

In particular, exchanging only a single guanylate for a locked nucleic acid (LNA) guanylate at the TSO 3′ end (rGrG+G), led to a 2-fold increase in cDNA yield relative to the SMARTer® IIA oligo used in commercial Smart-Seq (p=0.003, Student's t-test; FIG. 1a , Table 2 and FIG. 3).

Additionally, it was discovered that the methyl group donor betaine in combination with higher MgCl₂ concentrations had a significant positive effect on yield (2-4 fold increase, p=0.0012, Student's t-test, for all comparisons) (FIG. 1b ). The commercial Smart-Seq buffer has a final concentration of 6 mM MgCl₂, but it was found herein that higher yield is obtained when increasing the concentration to 9 mM or beyond. Finally, the average length of the preamplified cDNA increased with 370 nts when administering dNTPs prior to the RNA denaturation rather than in the RT master mix (p=7.8×10⁻⁹, Student's t-test; FIG. 1c ).

It was further demonstrated that these improvements obtained with purified RNA extended to cDNA reactions performed directly in lysates of individual human and mouse cells. To this end, single-cell cDNA libraries were generated from a total of 262 individual human or mouse cells (159 HEK293T, 34 DG-75, 30 C2C12 and 39 MEF cells) spanning different cell sizes and total RNA contents (Table 3). Analyses of the single-cell cDNA libraries demonstrated higher cDNA yields both with the use of the LNA-containing TSO (3-fold increase, p<0.001, Student's t-test; FIG. 1d ) and with betaine together with high Mg²⁺ concentrations (4-fold increase, p=3.7×10⁻⁶, Student's t-test; FIG. 1e ).

The sensitivity and accuracy of single-cell methods are limited by the efficiency of each sample-processing step. The SMARTer® protocol uses bead purification to remove unincorporated adaptors from the first strand cDNA reaction before the preamplification with Advantage 2 Polymerase (Adv2). However, performing bead purification in small volumes poses a significant recovery challenge for liquid handling automation. It was determined herein that KAPA HiFi Hot Start (KAPA) DNA Polymerase efficiently amplified first-strand cDNA directly after reverse transcription, with no need for prior bead purification. Libraries preamplified without bead purification had no reduction in yield, but the average cDNA length increased with 450 nts (p=2.6×10⁻¹², Student's t-test; FIG. 1f ) demonstrating that KAPA preamplification improves cDNA generation and offers a viable approach for Smart-Seq automation.

To demonstrate the significance of the improved cDNA generation on downstream applications, its impact on single-cell transcriptome profiling was assessed. To this end, single HEK293T cell libraries generated both according to the commercial SMARTer (n=4) and using variations of the present protocol were sequenced (Smart-Seq2, n=35) (Table 4).

The improved conversion of RNA to cDNA should improve gene expression profiling as more original RNA molecules are accessible for sequencing. Indeed, both a significant increase in the ability to detect gene expression (FIG. 2a ) and lowered technical variation for low and medium abundance transcripts were observed (FIG. 2b and FIG. 4). The improved sensitivity of the optimized protocol led to the average detection of 2,372 more genes in each cell (p<0.05 Student's t-test; FIG. 2c ). All these improvements were independently validated using an alternative RNA-Seq alignment and analyses strategy (FIG. 5). Moreover, both better sensitivity and lower variability in single-cell transcriptome data generated with Smart-Seq2 than for data available for Quartz-Seq were obtained (FIG. 6). Although the sequenced libraries had similar mappings characteristics as SMARTer libraries, a 7% increase in unmapped reads was noted (FIG. 7).

Several preamplification enzymes have lower GC bias than the Advantage2 (Adv2) that is used with SMARTer®, indicating that single-cell profiling could also improve with cDNA preamplifications using KAPA. Indeed, the single-cell libraries preamplified with KAPA detected more genes at higher GC levels (FIG. 2d and FIG. 8) and improved sensitivity and accuracy (FIG. 9). When compared with the low coverage of 5′ regions in single-cell data generated through 3′ end polyA-tailing of cDNA, single-cell RNA-Seq libraries that had been preamplified with KAPA had significantly better coverage across the full length of transcripts (p<10⁻⁵, 1.6×10⁻³ for 5′ and 3′ ends respectively, Student's t-test), as they approached the expected fraction of reads at the 5′ and 3′ ends (FIG. 2e and FIGS. 10-11). Importantly, global gene expression profiles from cells preamplified with KAPA and Adv2 separated on the first principal component (FIG. 2f ), demonstrating that preamplification bias had significant impact on absolute expression levels. Regions with artificially large number of reads aligned (i.e. peak) appearing systematically in Smart-Seq irrespectively of preamplification enzyme that necessitated filtering were sequenced (FIG. 12). Together, the data show that preamplification using KAPA improved GC tolerance and read coverage across transcripts.

To determine the extent of technical variability in the single-cell transcriptome profiling with Smart-Seq2, sequencing libraries were generated from dilution series of HEK293T cells (100, 50 and 10 cells) and total RNA (1 ng, 100 pg, 10 pg). Technical losses and variations were small when analyzing 10 cells or more, but considerable variability exists at single-cell levels, as previously observed. It is informative to contrast the technical variability with the biological variability present in cells of the same or different cell type origin (FIG. 13A-D). To this end, additional single-cell transcriptomes were sequenced from DG-75 (n=7), C2C12 (n=6) and MEF (n=7) cells. Analyzing the biological variability between and within cell populations revealed that biological variability associated with cell type specific expression exceeded technical variability at around 50 RPKM, but the exact threshold will depend on the RNA content present in the cell types studied (FIG. 13E).

This invention provides a new protocol that improves sensitivity, accuracy and coverage across transcripts and is more amenable to automation. Moreover, the new protocol costs less than 12% of the current cost per reaction and only 3% when using in-house produced Tn5 (FIG. 14).

Although these results were reached in the context of Smart-Seq single-cell gene expression analyses, these modifications are applicable other single-cell methods that rely on template switching, including those carried out on microfluidic chips (e.g. Fluidigm C1) or inside emulsion droplets.

The foregoing examples and description of the preferred embodiments should be taken as illustrating, rather than as limiting the present invention as defined by the claims. As will be readily appreciated, numerous variations and combinations of the features set forth above can be utilized without departing from the present invention as set forth in the claims. Such variations are not regarded as a departure from the spirit and script of the invention, and all such variations are intended to be included within the scope of the following claims.
